Book excerpt: We present an unitary dispersive model for the $\eta \to 3 \pi$ decay process based upon the Khuri-Treiman equations which are solved by means of the Pasquier inversion method. The description of the hadronic final-state interactions for the $\eta \to 3\pi$ decay is essential to reproduce the available data and to understand the existing discrepancies between Dalitz plot parameters from experiment and chiral perturbation theory. Our approach incorporates substraction constants that are fixed by fitting the recent high-statistics WASA-at-COSY data for $\eta \to \pi^+ \pi^- \pi^0$. Based on the parameters obtained we predict the slope parameter for the neutral channel to be $\alpha=-0.022\pm 0.004$. Through matching to next-to-leading order chiral perturbation theory we estimate the quark mass double ratio to be $Q=21.4 \pm 0.4$.

Available in PDF, EPUB and Kindle. Book excerpt: We compile 181 papers report p̄p, p̄n, p̄d, n̄p, n̄n, and n̄d reactions in flight for beam momenta up to 50 GeV/c. We display, as a function of incident momentum, total and channel cross sections, elastic and two-body inelastic differential cross sections, and polarization in elastic scattering, as well as our fits to the elastic differential cross sections. We also provide indices to the papers, as well as a complete listing of the selected data. The approximate cutoff date for the literature search for this report was September 1, 1971.
